Large, right lower lobe pneumatocele is shown, compromising ventilation in a premature infant with RDS and superimposed RSV pneumonitis. A pneumatocele is a cavity in the lung parenchyma filled with air that may result from pulmonary trauma during mechanical ventilation. [1] Gas-filled, or air-filled lesions in bone are known as pneumocysts. [2]
A focal lung pneumatosis is an enclosed pocket of air or gas in the lung and includes blebs, bullae, pulmonary cysts, and lung cavities. Blebs and bullae can be classified by their wall thickness. [1] A bleb has a wall thickness of less than 1 mm. [2] By radiology definition, it is up to 1 cm in total size. [3]
It is thin-walled and may appear as a small blister, more than 5 mm in diameter. It can also be referred to as a bulla. Some clinicians may also include milk blisters as a type of bleb. In addition, a blocked Montgomery gland may also be called a nipple bleb though its cause is different than a milk or serous-filled bleb on the nipple. [2]

Historically, tuberculosis was the most common cause of the lung cavity (and still is in areas where tuberculosis is endemic); [7] however, the cavity can also be caused by sarcoidosis, bullae, bronchiectasis, or cystic lung disease. [2] Chronic necrotizing aspergillosis and invasive aspergillosis are usually seen in immunocompromised people. [4]

In some lung diseases, especially emphysema, it is possible for abnormal lung areas such as bullae (large air-filled sacs) to have the same appearance as a pneumothorax on chest X-ray, and it may not be safe to apply any treatment before the distinction is made and before the exact location and size of the pneumothorax is determined.
